The bacterium produces substances that neutralize acids, forming a kind of protective cloud around it, allowing it to be locomova within the stomach until it finds a point to settle. Humans appear to be the principal reservoir of the bacteria, however, H.pylori has been isolated from other primates, sheep and domestic cats, suggesting that their transmission to humans could occur. The contaminated water, especially in developing countries, often serves as a source of bacteria.
When a family member is infected with Helicobacter pylori, the risk of transmission to their children and other members is very high. As has been mentioned earlier in this article, the H.pylori often becomes lodged in the wall of the stomach just below the protective layer of mucus. Currently there are several methods to diagnose the presence of the bacterium Helicobacter pylori. Recently, the indications for treatment of H.pylori were expanded, encompassing groups that until recently were not routinely treated.
After 4 weeks from the end of treatment, the patient can perform the noninvasive tests to confirm the elimination of bacteria.
Studies looking at bacteria in the stomachs of dogs and cats have found that Helicobacter species are extremely common, with some studies finding one or more species of Helicobacter in every dog or cat that was tested.
Studies looking at risk factors for Helicobacter infection in people have not identified pet ownership as a risk factor. A study comparing one Helicobacter species that has been mentioned as a possible zoonotic concern, H. While finding the same Helicobacter species in a person and his or her pet raises concern, studies have yet to demonstrate whether such findings are due to animal-to-human transmission, human-to-animal transmission, or infection of both person and pet from the same source. One question that is currently unanswered is whether the mouth of a dog or cat can be a source of Helicobacter infection, because the bacterium can be found in saliva. About The Centre for Public Health and Zoonoses offers information relating to zoonotic diseases (diseases transmitted from animals to people), including aspects of human and pet health, infection prevention and control, and vaccination.
In addition to this protection, the H.pylori can overcome the mucus barrier that the stomach has to protect itself from the acidity, clinging to the mucosa, the mucous area below where the acidity is much less intense. This layer is essential for protecting the stomach, preventing the hydrochloric acid impairs its mucosa.
They live in the stomach of humans and many animals, an environment that was previously thought to be completely inhospitable to bacteria. Since Helicobacter is an important problem in people, does that mean that we need to be worried about pets as a source of infection?
If there is any involvement of pets in this disease in people, it’s probably sporadic at most. Scott Weese and Maureen Anderson of the Ontario Veterinary College's Centre for Public Health and Zoonoses. Conservative estimates suggest that over 50% of the world population has the stomach colonized by these bacteria. The acidity of the stomach is one of the defense mechanisms of the body against bacteria that are ingested along with food. We know that transmission can occur from an infected person to a healthy person through contact with vomit or feces, the latter usually in the form of contaminated food or water.


Even in countries without universal sanitation, most children are infected before 10 years and the prevalence in the adult population becomes greater than 80%. There are strains of bacteria more aggressive and they are more indolent, which partly explains the occurrence of symptoms in only a few infected people. Just as an example, studies show that only 1 in every 14 patients complaining of burning stomach without gastritis or ulcer on endoscopy, improve with treatment for H. As in some places up to 90% of the population presents itself contaminated by bacteria, tests will be positive in almost everyone. However, in patients who complain of stomach pains, endoscopy is important to assess the condition of the stomach, also serving for the diagnosis of gastritis, ulcers or tumors. The relationship is so strong that the treatment of this tumor is done with antibiotics and eradication of the bacteria leads to a cure of this malignancy.
We now know that Helicobacter bacteria are beautifully adapted for survival in the stomach and are very common.
Avoiding contact with stool from pets and paying good attention to handwashing should decrease the risk even further. In developed countries like the United States and Europe, contamination in children is rare, but the transmission is common in adulthood, where over 50% of the population over age 60 years is infected.
Therefore, it makes sense to request research H.pylori in people without specific complaints.
Therefore, many of the diagnoses of Helicobacter pylori are still made by endoscopy, biopsy and by urease test. In people, Helicobacter pylori is an important cause of gastritis (inflammation of the stomach), stomach ulcers and stomach cancer. The photos below show how the stomach commonly looks and what may be seen under the microscope when the stomach is biopsied. These actions cause inflammation of the stomach lining, leading to gastritis and in some cases, to the formation of peptic ulcers and even tumors. The non-invasive tests are eventually used more after treatment in order to confirm elimination of bacteria. Therefore, treatment is not indicated against Helicobacter pylori to everyone who has the bacteria. A fact that speaks against this form of transmission is that dentists do not have higher infection rates than other traders who deal constantly with saliva and bacterial plaque. Only patients with a family history of gastric cancer should worry about the presence of asymptomatic H. Rarely gluten can cause inflammation of the stomach though usually the area affected by gluten is the first part of the small intestine also known as the duodenum. In these cases even if the patient does not present any symptoms, the research and treatment of the bacteria are indicated in order to eradicate it. It is the area of the stomach that is most prone to infection from Helicobacter pylori, the bacteria that predisposes to stomach, ulcers and stomach irritation from aspirin or other medications. The pylorus is the opening leading from the stomach to the first part of the small intestine.
If present in context of symptoms, ulcers or a family history of stomach cancer or ulcers, H.


Chemical irritation of the stomach, also known as reactive gastropathy or gastritis, is common. Aspirin and aspirin like arthritis or anti-inflammation or pain relieving medications known as non-steroidal anti-inflammatories (NSAIDS) commonly cause reactive gastropathy or chemical gastritis. So acid blockers (zantac, tagamet, pepcid, prilosec, nexium etc) don't relieve the pain. It is made by the liver and secreted from the bile ducts and gallbladder into first part of the small intestine known as the duodenum. It is normally not in the stomachA but can regurgitate backwards from the duodenum through the pylorus into the stomach. The stomach usually appears reddened (erythema) and granular and bile is usually seen (as greenish fluid) in the stomach. The bacteria Helicobacter pylori likes to burrow under this mucus layer and triggers increase inflammation type cells in the stomach lining. The bacteria can trigger changes that make the stomach vulnerable to ulceration was well increase the risk of stomach cancer and a type of lymphoma of called MALT lymphoma.
That lymphoma, a form of cancer, can be cured frequently with just antibiotics to rid the stomach of H. However, these are common symptoms that can be due to other conditions, and some are even experienced by healthy people from time to time: excessive burping feeling bloated feeling sick or vomiting losing your appetite losing weight Although common, if any of these symptoms persist, or if they are causing you concern, it is always best to see your doctor. If you notice blood or a black color in your feces or vomit, you should consult your doctor.
What does the stomach normally look like visually?The stomach has slightly salmon pink to orange-red color on surface.
It is common for some redness to be present since it does contain acid and other digestive juices. Stool Tests A stool sample may be needed to check for signs of Helicobacter pylori in your feces. Most ulcers occur in the antrum of the stomach, within in the pylorus or in the first portion of the duodenum known as the duodenal bulb. Breath Tests If you have a breath test, you will swallow a preparation containing radioactive carbon.
The bacteria Helicobacter pylori likes to infect the antrum of the stomach, where it can burrow underneath the protective mucus layer of the stomach and cause inflammation that predisposes to ulceration, cancer and lymhoma of the stomach.This page is a work in progress explaining gastritis and gastropathy.
Endoscopy A long, thin instrument called an endoscope is inserted into your mouth and fed down into your stomach and duodenum. In most cases, only one round of antibiotics is needed to clear the infection but, occasionally, you might need to take more, using different drugs. Treatment may not cure the infection if a person has a stomach or duodenal ulcer or stomach cancer. For those who develop these diseases, the outlook will depend on the problem, how soon it is diagnosed, and how it is treated.
